Node Configuration

During the procedure, when you are asked to fill some fields as country or e-mail, you can leave them blank.

Configuration File

Initialize the application configuration (the below command creates and populate config.toml file)

sudo docker run --rm \
    --volume ${HOME}/.sentinelnode:/root/.sentinelnode \
    sentinel-dvpn-node process config init

Open the configuration config.toml file

sudo nano ${HOME}/.sentinelnode/config.toml

Edit the required fields

Important

Do not copy and paste the entire code block as it may disrupt the configuration file!!! Only copy the necessary fields or add them manually!

The fields gigabyte_prices and hourly_prices must encompass the entire string, including the IBC coins as well separated by commas. Merely incorporating the udvpn price will not suffice.

Please find below the list of supported IBC coins from Sentinel along with their corresponding denom variables:

Node Type

Depending on the node type you specified in the config.toml file, use the corresponding configuration settings.

Wireguard

Initialize the WireGuard configuration

sudo docker run --rm \
    --volume ${HOME}/.sentinelnode:/root/.sentinelnode \
    sentinel-dvpn-node process wireguard config init

Open the wireguard.toml file

sudo nano ${HOME}/.sentinelnode/wireguard.toml

Take note of the WireGuard port

wireguard.toml

# Name of the network interface
interface = "wg0"

# Port number to accept the incoming connections
listen_port = <wireguard_udp_port> #for example listen_port = 8888
# this is the WireGuard UDP port, you can change it and write it down as you need it later

# Server private key
private_key = "TwkdSO6cax3Sbo06mvmMyd2X452usVeVDTK/hdkfOmI="

V2Ray

Initialize the V2Ray configuration

sudo docker run --rm \
    --volume ${HOME}/.sentinelnode:/root/.sentinelnode \
    sentinel-dvpn-node process v2ray config init

Open the v2ray.toml file

sudo nano ${HOME}/.sentinelnode/v2ray.toml

Take note of the V2Ray port

v2ray.toml

[vmess]
# Port number to accept the incoming connections
listen_port = <v2ray_tcp_port> #for example 9999
# this is the V2Ray TCP port, you can change it and write it down as you need it later

# Name of the transport protocol
transport = "grpc"

Add a Mnemonic

Add an account key (the one in config.toml file)

docker run --rm \
    --interactive \
    --tty \
    --volume ${HOME}/.sentinelnode:/root/.sentinelnode \
    sentinel-dvpn-node process keys add

if you already have a mnemonic and simply want to recover your account, type this

docker run --rm \
    --interactive \
    --tty \
    --volume ${HOME}/.sentinelnode:/root/.sentinelnode \
    sentinel-dvpn-node process keys add --recover

You will be prompet to select a passphrase

You will be provided with an operator address (sent1), a node address (sentnode1), and a mnemonic phrase that you should write down and store in a secure location.

Move created TLS keys

sudo mv ${HOME}/tls.crt ${HOME}/.sentinelnode/tls.crt && \
sudo mv ${HOME}/tls.key ${HOME}/.sentinelnode/tls.key

sudo chown root:root ${HOME}/.sentinelnode/tls.crt && \
sudo chown root:root ${HOME}/.sentinelnode/tls.key

Enable Firewall Ports

Enable TCP port on Firewall (check file config.toml)

sudo ufw allow <tcp_port>/tcp #for example sudo ufw allow 7777/tcp

(Wireguard) Enable UDP port on Firewall (check file wireguard.toml)

sudo ufw allow <udp_port>/udp #for example sudo ufw allow 8888/udp

(V2RAY) Enable TCP port on Firewall (check file v2ray.toml)

sudo ufw allow <tcp_port>/tcp #for example sudo ufw allow 9999/tcp

Enable Port Forwarding (for Residential Nodes)

If you're hosting your node from home, make sure to enable port forwarding on your router to allow external access. To do this, access your router settings and navigate to WAN services, then add the following two IPv4 Port forwarding table entries:

Name            ProtocolWAN     Port                    LAN port                Destination IP
TCP_PORT        TCP             <tcp_port>              <tcp_port>              your_local_ip
WIREGUARD_PORT  UDP             <wireguard_udp_port>    <wireguard_udp_port>    your_local_ip
V2RAY_PORT      TCP             <v2ray_tcp_port>        <v2ray_tcp_port>        your_local_ip
